  1. 16. Modern landfill leachates – quality and treatment

    Författare :Hanna Modin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy metals; European Landfill Directive; Biodegradation; Landfill leachate; Leaching tests; Multivariate data analysis; Organic matter; Sorption filters;

    Sammanfattning : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. LÄS MER

  3. 17. Optical sensors in drinking water production : Towards automated process control in relation to natural organic matter

    Författare :Claudia Cascone; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Access to safe and clean drinking water is a basic human right (A/RES/64/292). In Sweden, large drinking water treatment plants use mainly surface water as water source. The long-term trend of increasing natural organic matter (NOM) in boreal and north European surface waters negatively affects the overall performance of the treatment processes. LÄS MER

  4. 18. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Författare :Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Nyckelord :biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. LÄS MER

  5. 19. Removal of Natural Organic Matter to reduce the presence of Trihalomethanes in drinking water

    Författare :Indiana Garcia; Luis Moreno; Bhekie B. Mamba; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Sammanfattning : In countries located in tropical zones, a critical task in drinking water plants is the removal of the natural organic matter (NOM), particularly during the rainy season when a lot of organic matter is transported by run-off into the water bodies. It provokes overloaded in the plants and they have often needed to be shut down. LÄS MER

  7. 20. Treatment methods for the removal of per- and polyfluoroalkyl substances (PFASs) from drinking water : optimizing existing and exploring novel treatment techniques

    Författare :Vera Franke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Worldwide, the demand for safe drinking water is rising. As drinking water sources are increasingly impacted by anthropogenic and environmental changes it is becoming a challenge to produce safe and clean water. LÄS MER
